Tip

When using this board with RIOT, set the BOARD variable to p-nucleo-wb55 in your Makefile. If you follow the standard RIOT project structure, your Makefile should look like this:

./Makefile

# name of your application
APPLICATION = hello-world

# Change this to your board if you want to build for a different board
BOARD ?= p-nucleo-wb55

# This has to be the absolute path to the RIOT base directory:
RIOTBASE ?= $(CURDIR)/RIOT

include $(RIOTBASE)/Makefile.include

Support for the STM32 P-Nucleo-WB55

Overview

The p-nucleo-wb55 is a multi-protocol wireless and ultra-low-power device embedding a powerful and ultra-low-power radio compliant with the Bluetooth® Low Energy (BLE) SIG specification v5.0 and with IEEE 802.15.4-2011 board. It integrates an ARM Cortex-M4 STM32WB55RG microcontroller with 256KB of RAM and 1MB of ROM Flash.

You can find general information about the Nucleo64 boards on the boards_common_nucleo64 page.
